as far as russia is concerned, why kill kennedy? he took him to the cleaners in the cuban missile crisis. he says in the memoirs learning kennedy was killed, he we want. there's not any evidence that the soviets or cubans were involved in the murder of john f. kennedy. only two weeks ago, our esteemed secretary of state, john kerry, says in an interview with cnn, i never thought oswald acted alone, right about that part. i think the russians and the cubans did it. completely wrong. another question. >> you mentioned briefly the possible setups in chicago and tampa. was there a hit team in tampa and kennedy's campaign appearance was canceled because of that, or is that wrong? >> i think they canceled the motorcade putting him at risk, but in both cases, secret service learned of attempts and changes made to the president's schedule to avoid exposure, but there is no way to avoid the fact that in dallas, secret service acts in a very strange way. i personally have been involved in 13 trips on behalf of presidents of the united states,
